That's not a good sign, and the OP of this thread is not anymore active, last active on June 23, 2020,.. so probably they stop updating this thread when they failed to address the scam accusation against them.
So it is confirmed now that Jetwin turn into scam, what a bad thing for bitcoin gambling industry.
As one of the oldest bitcoin casinos, Jetwin should have served their players better but what we see now is the opposite.
Just checked their twitter account and they are still active (last tweet was 5 hours ago) so it is clear that they do not want to come here because of the accusation but they still try to get players through social media.
Just refer to the thread (scam accusation against JETWIN ) posted by freedomgo here, and make your own judgement. IMO, since they did not reply when they have an appearance in the forum, then that would make me doubt their reputation, but since their site is still online, then we might say they have not gone full scam yet but probably sooner, so we have to be careful.
